| What Is a Good Linear Finite Element? - Jonathan Why are elements with tiny angles harmless for interpolation, but deadly for stiffness matrix conditioning? Why are long, thin elements with angles near 180o terrible in isotropic cases but perfectly acceptable, if they're aligned properly, for anisotropic PDEs whose solutions have anisotropic curvature? Why do elements that are too long and thin sometimes offer unexpectedly accurate PDE solutions? Why can interpolation error, discretization error, and stiffness matrix conditioning sometimes hav...

When the flow on smooth manifold is characterized as vector field then one would expect that the flow remains stable for time as much possible as we wish. But, this is too much a requirement several topological constraints will come in the way of such smooth flows. We have made a note of this fact interms of global solvability.
